Abstract

Chromatic uniformity is a key indicator of splicing projection system. The splicing laser projection system is reported which consist of five splicing subsystems. The total projection area covers 100 square meters and the system has total flux output of 75000lm. The fluctuation of luminance is 2% and chromaticity drift Δx2+Δy2=0.002 with the auto white balance controller we designed.
